BleepingComputer.com: Can't get My MSN.com

I have a Sony Vaio Windows XP laptop computer. I also use Mozilla Firefox for my browser. I have been using mymsn.com as my home page for many years. Suddenly last week, (it seems like when Windows 7 was put on the market) I could not get this website on Firefox. In fact, it does show up on IE but when I put the address in my firefox address bar, I get this:Your request could not be processed at this time, please refresh this page or try again later. It shows this message every time and this is so aggravating because I always look forward to its lovely features like the weather in different areas, tennis news, etc. Could anyone help me get this back as my homepage? Thanks for your help.
